3 Glaims.

This invention relates to brushes and has particular reference to a brush adapted to discharge a liquid onto the bristles as the brush is used in the cieaning operation.

An object of the invention is to provide a brush with a reservoir in the head thereof adapted to receive cleaning fluid and the like and which is discharged onto the bristles by the movement of the brush in the cleaning operation.

Still another object of the invention is to provide a brush of said character in which the amount of cleaning fluid supplied to the brush head can be regulated as desired.

Still another object of the invention is to provide a brush for cleaning floors, carpets and the like which is eflicient for its purpose, which can be produced at small cost and which is convenient to operate.

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a perspective view of a brush constructed in accordance with the invention.

Fig. 2 is a horizontal sectional view taken approximately on line 2-2 of Fig. 3.

Fig. 3 is a transverse sectional view taken approximately on line 3-3 of Fig. 2.

Fig. 4 is a fragmentary sectional view taken approximately on line 4- of Fig. 2.

Referring to the drawings by characters of reference, the brush includes a head ii] consisting of a receptacle I i and a cover 12 fitted thereover so as to close the top thereof. The receptacle H includes a bottom wall is and a peripheral wall it while the cover 52 includes a top wall l5 and a peripheral wall it which slidably fits the peripheral wall Hi of the receptacle II and with the top wall l5 disposed in covering relation on the top of the peripheral wall IS. The cover I2 is secured in covering relation on the receptacle it by studs l8 aifixed to the bottom wall l3 of the receptacle and engaging upwardly through openings l9 in the top wall with the threaded outer ends of said studs engaged by wing nuts it. The brush head it is provided with a handle 22 secured to the top wall of the cover i2 by a flanged socket 23.

In order to provide means for feeding a liquid such as a cleaning fluid to bristles 24 depending from the underside of the bottom wall 13, a supply tank 25 is secured to the handle 32 and connected to the lower end thereof is a feed tube 26 having its lower end extending through the top wall 15 and with the outlet 21 opening into the receptacle H. The bottom wall [3 of the receptacle is formed with longitudinally extending upwardly projecting ribs or ridges 28, two being shown in the present embodiment which are disposed in parallel relation and spaced apart to provide a trough 29 therebetween. The ends of the trough are closed by the end walls of the reservoir and the trough is located centrally below the outlet end 21 of the feed tube 26. The bottom wall i3 is also provided with two rows of apertures 31! which open downwardly therethrough and are arranged substantially midway between the ribs or ridges 28 and the side walls oi the receptacle. This provides means by which the cleaning fluid admitted to the receptacle through the feed tube 26 collects in the trough 29 and when the brush is used in the cleaning operation, the liquid will splash over the ribs or ridges 28 and flow downwardly through the rows of apertures 30 and onto the bristles 24.

The supply tank 25 is provided with a cap 3! for closing the filling opening in the upper end thereof and which cap may be of the standard type having an air vent for admitting air to the supply tank as the cleaning fluid is discharged therefrom. A regulating valve 32 is connected in the feed tube 26 for regulating and closing ofi the flow of the cleaning fluid from the supply tank.

What is claimed is:

1. In a brush of the character described, a brush head including a receptacle having a bottom wall-provided with parallel ridges in the upper face thereof forming a central recess therebetween and outer recesses on the outer sides of said ridges respectively and said bottom wall hav ing apertures opening into said outer recesses and extending downwardly through the lower face thereof, bristles secured to and depending from said bottom wall, and means for feeding liquid to said central recess whereby the liquid will be splashed over the ridges and will flow downwardly through said apertures onto the bristles when the brush is operated.

2. In a brush of the character described, a brush head including a receptacle having a bottom wall formed with a plurality of recesses in the upper face thereof and having apertures opening into one of said recesses and extending downwardly through the lower face or" said wall and the other of said recesses being imperforate, bristles secured to and depending from said bottom wall, and means for feeding liquid to the imperforate recess whereby the liquid will be splashed from said last named recess into the apertured recess and will flow downwardly through the apertures therein onto the bristles when the brush is operated.

3. In a brush of the character described, a brush head inluding a receptacle having a bottom wall provided with a longitudinally extending mp lna recess the upp r face th reof, nd said bottom wall having a sideportion extending longitudinally of said recess and formed with apertures opening into said receptacle and extending downwardly through the, lower face thereof, bristles secured to and depending from said side portion, and means for feeding liquid; 6Q 15 4 said recess whereby the liquid will be splashed from said recess upon said side portion by movement of the brush in a cleaning operation and will flow downwardly through said apertures onto 5 the bristles.
